GB/Z 45268-2025 Guidelines for principal component reliability testing for LED light sources and LED luminaires
Abstract
This document provides reliability test guidelines for LED light sources and LED luminaires used in general lighting. It includes methods for initial qualification tests and accelerated stress tests of major components.
Note: The performance of any major component can affect the performance of the final product.
Techniques for determining the declared lifespan and predicting the maintenance rate of luminous flux are beyond the scope of this document.
The major components of LED light sources or LED luminaires used in the tests include the following:
—— LED packages and connectors;
—— Optical materials;
—— Electronic components;
—— Active (e.g., fans) and passive (e.g., thermal interface materials) cooling systems;
—— Structural materials.
